Description

Data scheduling method and device

The present invention relates to the field of Internet technologies, and in particular, to a data scheduling method and apparatus. Background technique

The current video service and Web browsing are burst Burst-based services. For example, when a client clicks on a link and initiates a Hyper Text Transfer Protocol (HTTP) request to obtain a web page, a window is required at the client. After all the packets (ie a Burst) have been fully rendered.

Currently, the link layer scheduling is located at the Media Access Control (MAC) layer, which is packet-based scheduling. To ensure the user experience, the scheduling usually sets a delay limit for each packet, that is, each packet for the Burst needs to be transmitted within the delay limit. However, setting a delay for each packet limits the flexibility of scheduling. Moreover, because Burst's delay is not only related to the delay of each packet, but also related to bandwidth, even if each packet satisfies the delay limit, it does not necessarily guarantee the delay of the entire Burst, and the transmission efficiency is low.

S102: The network device acquires pulse Burst data of the service indicated by the service request according to the service request.

In a specific embodiment, the Burst data of the current service request corresponding service may be obtained from the related application server. Further, if the current UE and the application server are connected by a Transmission Control Protocol (TCP), the Burst data corresponding to the service can be quickly downloaded from the server by deploying a TCP Proxy, that is, a TCP proxy.

S103: The network device acquires service identification information of the service according to the service request. The service identification information includes at least a size of the burst Burst data and delay requirement information of the Burst data.

Optionally, the current eNodeB may trigger the service identification information of the service request corresponding to the service request when the UE initiates the service request. Specifically, the method for obtaining the service identification information may be: performing a deep packet inspection (DPI) on the service request, detecting the application layer of the service, or obtaining the information by using another information identification method. The embodiment of the invention is not limited.

Optionally, the current network device, such as an eNodeB, that is, a radio access network (RAN) side, may also perform DPI detection on the Burst data, thereby obtaining service identification information such as the size and time delay requirement of the Burst data. .

S202: The network device acquires pulse Burst data of the service indicated by the service request according to the service request.

In a specific embodiment, the network device, such as the eNodeB, can obtain the service indicated by the service request by parsing the service request, and obtain the Burst data corresponding to the service from the server. Specifically, the eNodeB can obtain the specific service corresponding to the request by parsing the received user request, for example, the parsing result is a certain web service or video service, etc., thereby instructing the corresponding application server to download and obtain the web service. Or Burst data corresponding to the video service.

In a specific embodiment, different transport layer protocols have different requirements for establishing a transport connection. For example, for the TCP protocol, a TCP connection needs to be established before transmitting a data packet carrying data, and for a User Datagram Protocol (User Datagram Protocol, UDP ), you do not need to establish a connection in advance.

Further, if the UE is connected to the server through a transmission control protocol (TCP), the slave server obtains the Burst data corresponding to the service indicated by the service request, and may deploy the TCP proxy according to the TCP connection, and The TCP proxy downloads Burst data corresponding to the service indicated by the service request from the server.

Further, for the video stream, the code rate and the time slice corresponding to the video service may be obtained, and the size of the Burst data corresponding to the video service may be estimated according to the code rate and the time slice.

Further, the Burst number corresponding to the service is set according to the service type. According to the delay requirement, if the service type is a video service, the time slice corresponding to the video service may be used as the delay requirement of the Burst data corresponding to the service, for example, the time slice corresponding to the video is 20s, the delay requirement of the Burst data can be set to 20s. Optionally, if the service type is a webpage service, the matching test result obtained by performing the service delay test on the webpage service may be obtained, and the Burst data corresponding to the webpage service is set according to the matching test result.
